721 Height

I was reorganizing a bunch of my stamps and happened to notice a 3 cent G. Washington - Scott 721, that was noticeably taller than 4 other 721s I had. Not hugely - maybe .5mm, but I definitely noticed the difference. I know I wouldn't have noticed except that the 721 is a coil stamp, perf 10V, so it has straight edges on the top and bottom.

Is this abnormal? I compared a bunch of 722s and couldn't notice any difference in the width, but I just don't know. Any Feedback?

coils are all made standard size from straight edge to straight edge so they will work in machines etc. You may have a regular 720 that has been trimed

Jim,

If it were a 720, then it would have to be re-perfed also, since the 720 is 11 x 10 1/2, and there's probably too much margin on my 721 for that.

Weird.

The height of rotary coils may vary somewhat depending on how the cutting knives happen to be spaced. It is also possible for coils to exist with an irregular edge if the paper web wanders too far to the right or left. Since a horizontal rotary coil is wider and shorter than a rotary sheet stamp or vertical coil, there is not much likelihood that a philatelist would confuse one for the other. In addition to providing no real economic benefit, any attempt to fake a 721 coil would be unconvincing and ultimately unsuccessful. It would be helpful if posts here were fact checked before being submitted.

I was just putting it out as a possibility, I'm sure nobody would fake one but what a secratary may have done with a pair of scissors way back when it came out is another story. If the perfs are right you prob should keep in your oddities.
